The types of battery charger

On the market there are many types of battery charge: rechargeable alkaline battery charger, Ni-MH battery charger, types of nickel-cadmium battery charger. Suggested that you can buy when you purchase battery charger multi-function battery charger, you can reduce some of the costs.

Car charger is of ten referred to as car charger. On the GPS Navigator car charger is mainly used in the car. His exquisite design, small size, easy to carry, and loved by the majority of free driving. General car charger AC (input voltage) 12V DC (output voltage) 5V DC (output current) as 300~400 Ma.

The types of battery charger

Nickel cadmium battery (Ni-Cd)

Voltage: 1.2V

Service life: 500 times

Discharge temperature: -20 degrees to 60 degrees

The charging temperature is 0 degrees to 45 degrees.

Note: strong ability to resist.

Nickel hydrogen battery (Ni-MH)

Voltage: 1.2V

Service life: 1000 times

Discharge temperature: -10 degrees to 45 degrees

The charging temperature is 10 degrees to 45 degrees.

Note: the current maximum capacity is about 2100mAh.

Li ion battery (Li-lon)

Voltage: 3.6V

Service life: 500 times

Discharge temperature: -20 degrees to 60 degrees

The charging temperature is 0 degrees to 45 degrees.

Note: the weight ratio of 30% to 40% light battery, the capacity is higher than 60%. But not battery overcharge, if the overcharge will cause high temperature structural damage = explosion.

Lithium polymer battery (Li-polymer)

Voltage: 3.7V

Service life: 500 times

Discharge temperature: -20 degrees to 60 degrees

The charging temperature is 0 degrees to 45 degrees.

Note: the modified lithium battery, no liquid, and the use of polymer electrolyte can be made into various shapes than lithium batteries.

Lead acid battery (Sealed)

Voltage: 2V

Service life: 300 to 200 times

Discharge temperature: 0 degrees to 45 degrees

The charging temperature is 0 degrees to 45 degrees.

Note: is the general car battery (it is in series with 6 12V), the battery life of 10 years without water, but the volume and the maximum amount is the largest.
